Abstract

A system and method for assembling a lancing device, and a lancing device fabricated according to such a system or method. A rotating disk is applied to a spring component and/or to a carrier component of the lancing device to mount the spring onto the carrier component.

Claims

1. A system for assembly of a lancing device, the lancing device comprising a carrier component and at least one spring to be mounted to the carrier component, the system comprising a disk for engaging at least a portion of the spring, and a drive mechanism for rotationally driving the disk, wherein the disk has a hardness selected to grip the spring and mount it onto the lancet carrier.

2. The system of claim 1, wherein the disk at least partially comprises rubber.

3. The system of claim 1, wherein the drive mechanism comprises an electric motor.

4. The system of claim 1, wherein the drive mechanism is at least partially contained in a housing.

5. The system of claim 1, wherein the disk comprises a contact surface having a Shore A durometer of between about 35-95.

6. The system of claim 1, wherein the disk comprises a contact surface having a Shore A durometer of between about 35-65.

7. The system of claim 1, wherein the disk comprises a contact surface having a Shore A durometer of between about 40-50.

8. The system of claim 1, wherein the disk comprises a contact surface having a Shore A durometer of between about 40.

9. The system of claim 1, wherein the disk comprises a contact surface having a Shore A durometer of between about 50.

10. A system for assembly of a device having a carrier component comprising a shaft and a retainer portion at an end of the shaft, and further comprising a spring mounted onto the shaft of the carrier component, the system comprising:

a disk having an outer radial contact face comprising a material having a Shore A durometer of between about 35-95; and

a motor coupled to the disk to rotationally drive the disk;

wherein application of the spring against the contact face of the disk spins the spring over the retainer portion of the carrier component and onto its shaft.

11. The system of claim 10, wherein the outer radial contact face has a Shore A durometer of between about 35-65.

12. The system of claim 10, wherein the outer radial contact face has a Shore A durometer of between about 40-50.

13. A method of assembly of a lancing device, the assembly method comprising applying a spring into partial assembly with a carrier component of a lancing device, engaging the spring with a rotating disk portion of a lancing device assembly system, and further assembling the spring onto the carrier component by operation of the rotating disk portion on the spring.

14. The assembly method of claim 13, wherein the step of applying a spring into partial assembly with a lancet drive component of a lancing device comprises manually installing a lead-in portion of the spring onto the lancet drive component.

15. A lancing device comprising a carrier component and at least one spring, wherein the lancing device is assembled by installing the at least one spring onto the carrier component by winding the spring onto the carrier component using a rotating disk that is applied against at least a portion of the spring and/or against at least a portion of the carrier component.

16. The lancing device of claim 15, wherein the lancet carrier comprises a forked end having first and second prongs, each of the first and second prongs having a barbed retainer thereon for retaining the spring.

17. The lancing device of claim 16, wherein the lancet carrier further comprises a cylindrical receiver or resilient collar opposite the forked end for releasably engaging a disposable lancet.

18. The lancing device of claim 17, wherein the lancet carrier further comprises a cantilevered arm extending therefrom at a medial portion between the cylindrical receiver and the forked end.

19. The lancing device of claim 17, wherein the lancet carrier further comprises a circumferential flange projecting outwardly from a medial shaft portion between the cylindrical receiver and the forked end.

20. The lancing device of claim 15, comprising a drive spring and a return spring, the drive spring being installed around a first shaft portion of the lancet carrier and the return spring being installed around a second shaft portion of the lancet carrier.
